Flow of Fluids Unit (Continuous Reactors)

Pignat's Flow of Fluids Unit (Continuous Reactors - RAP/4000) is a large-scale, modular, hydraulic network allowing for a broad range of experimental activities relating to the flow of an incompressible fluid (water) through piping systems.

This self-contained system facilitates the study of pressure drop due to flow restrictions through valves, strainers, fittings, and pipe of varying diameters, different surface roughnesses, and lengths. The system also facilitates the study of flow rate measurement methods such as orifice assembly, venturi meter, variable-area flow meter, and by calibrated tank vs. time.

Features

• Study and comparison of four continuous reactors from two different experiments:
  • Monitor the dispersion (NaCl) in water for determination residence time
  • The saponification of ethyl acetate by soda

Instrumentation

• 2 flowmeters
• 2 conductivity probes
• 2 temperature probes Pt100Ω

Specifications

• Two diaphragm pumps, variable flow rate
• Two glass vessels for constant feed by overflow
• Variable rate stirrer, SS stirring shaft with SS four blades helix
• 3 stirred glass reactors, pipe overflow, conductivity and temperature, drain valve and tracing injection: one 0.8L perfectly-stirred reaction vessel; and two 0.4L perfectly-stirred cascade vessels
• 2 plug glass reactors, 0.8L, conductivity and temperature measurement and tracer injection: one reactor coil, empty; and one reactor piston, packed
